[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 -J{Dxz  
y#&$f  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： W^003*m~~K  
enableservice('AutomationServer', true)
n}=rj7  
enableservice('AutomationServer') 4}+xeGA$  
kV_#9z7%  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 Z+r%_|kZ

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： ,Y$F

1. 在FRED脚本编辑界面找到参考. ,tcP=fdk]  
2. 找到Matlab Automation Server Type Library 7WgIhQ~  
3. 将名字改为MLAPP JL?Cnk$!

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 *Kp}B}}J

1. 创建Matlab服务器。 N$C{f;xV  
2. 移动探测面对于前一聚焦面的位置。 oG+K '(B

3. 在探测面追迹光线 _{lx*dq  
4. 在探测面计算照度 Jq=00fcT+  
5. 使用PutWorkspaceData发送照度数据到Matlab g@<sU0B  
6. 使用PutFullMatrix发送标量场数据到Matlab中 gCg4;b6g  
7. 用Matlab画出照度数据 Y0@'za^y  
8. 在Matlab计算照度平均值 c9\B[@-q  
9. 返回数据到FRED中 8.*\+n
